Introduction:
Biologic therapies treat patients with moderate to severe inflammatory bowel disease (IBD). This study aims to investigate the demographics of biologic therapy use and its association with patient characteristics, a topic that has not yet been thoroughly assessed in our region.
Methods:
Electronic health record data from June 1, 2021, to May 31, 2023, were collected at a tertiary care IBD center in Kuwait. The primary outcome of this single-center cross-sectional study was to assess the demographics of use of various biologic therapies among patients with IBD. The secondary outcome was to assess whether the type of biologic therapy differed based on gender, age, and IBD type.
Results:
Among the 513 patients using biologic therapy in this study, there were 210 (40.9%) on adalimumab (ADL), 154 (30.0%) on infliximab (IFX), 112 (21.9%) on ustekinumab (UST), and 33 (6.4%) on vedolizumab (VDZ). Patients taking VDZ were more likely to have ulcerative colitis (UC) (p < 0.001) and were more likely to be over 30 years old (p < 0.001). In contrast, patients on UST were less likely to be over 30 (p = 0.011) and more likely to have Crohn's disease (CD) (p < 0.001). In addition, patients on ADL were more likely to have Crohn's disease (p = 0.003), as were patients on IFX (p < 0.001).
Conclusion:
Patients taking VDZ were more likely to have UC and be over 30 years of age, while those on UST were more likely to be under 30 years of age and to have CD. Additionally, patients on ADL and IFX were more likely to have CD. This study highlighted the need for further research evaluating physicians' preferences and the effectiveness of different biological therapies in patients with IBD.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
